To all whom it may concern:

Be it known that I, TILLIAM F. GUL- NERICH, a citizen of the UnitedStates, and a resident of Meriden, in the county of New Haven and Stateof Connecticut, have invented a new and Improved Ventilator, of whichthe following is a full, clear, and exact description.

This invention relates to ventilators, and has for its principal objectsto provide a ventilatoradapted to be attached to a window, and to permitthe ingress of air into the interior of a building without causing adraft, at the same time keeping out all objectionable foreign mattersand substances,

and to providesuch a ventilator with means for regulating the influx ofair to the extent desired. Such objects I accomplish by the meanshereinafter described and illustrated in the accompanying drawings, inwhich similar characters of reference indicate similar parts throughoutthe several views.

In the drawings, Figure 1 represents a front elevation of a ventilatorembodying my invention attached to a window, shown partly broken away;Fig. 2 is a plan view of the ventilator shown in Fig. 1, enlarged;

Fig. 3 is a vertical longitudinal section taken on the line 3-3 of Fig.2; Fig. 4 is a vertical transverse section taken on the-line 44 of Fig.2; Fig. 5 is a similar view of my invention to that shown in Fig. 4,with the guard or shield closed; Fig. 6 is a fragmentary section of afront elevation of my device showing a shield and locking mechanismtherefor; Fig. 7 is a longitudinal seotion of a sliding latch andconnecting parts; and Fig. 8 is a perspective view of a latch forholding the guard or shield in place.

As illustrated in the drawings, 1 represents a window casing havingsashes 2 of ordinary construction connected therewith, and provided withwindow panes 3. The sash is also preferably provided with a pane ofglass 4 shorter in length than the adjacent panes 3, and the lower edgeof said pane bears against a bracket 5 extending longitudinally of theventilator. The bracket. 5 may be attached to the upper plate 6 of themain frame of the ventilator in any suitable manner, or if desired maybe formed integral therewith. The upper plate 6 is preferably formedintegral with a front plate '7 arranged at an acute angle to-the plate6, and with said Specification of Letters Patent.

plate 6 extending lengthwise of the ventilator. The ventilator is alsopreferably provided with a bottom plate 8 which is secured in anysuitable manner at its inner margin to the window sash. End plates 9 areattached to the longitudinal plates of the ventilator or formed integraltherewith. The upper plate 6 and front plate 7 of the ventilator areprovided with apertures 10 which are protected by a screen 11 preferablyarranged on the inner side of said top plate 6 and front plate 7 for thepurpose of preventing objectionable foreign matter from passing throughsaid apertures. A slide is mounted upon the top and front plates of theventilator, and is preferably formed of an upper plate 12 and frontplate 13 bent at an acute angle to each other and having their edgesheld and guided in grooves or ways 14. The upper and front plates of theslide are provided with apertures 15 corresponding with and adapted toregister with the apertures 10 of the top plate 6, and front plate 7, sothat when the apertures of the slide are brought into position toregister with the apertures of the main frame or top and front plates ofthe ventilator, air is permitted to freely pass through the frame of theventilator into the interior of the building. By moving said slidelongitudinally of the main frame of the ventilator the area of theapertures 10 of the main frame may be varied so as to regulate thequantity of air that may be permitted to pass through the ventilator.

The slide is so constructed that if desired the openings 10 in the mainframe of the ventilator may be entirely closed. A shield is pivotallymounted upon the main frame of the ventilator by means of studs 16, andsaid shield consists of a front plate 17 and lower plate 18 preferablyformed integral with each other and with end plates 19, as shown incross section in Figs. 4 and 5. The lower plate 18 of the shield ispreferably provided with a latch 20 which is held normally pressedoutward by means of a spring 21, said latch and spring preferably beinginclosed within a casing 22 attached to the lower plate 18 ofthe shield.The outer end of the latch 20 is preferably provided with a lip 23adapted to engage the edge of a latch 24. The latch 24 is pivotallymounted on the main frame of the ventilator by means of a stud 25 so asto permit the free end of said latch to have a lateral movement. Thelatch 24 is provided with pins adapted to engage a small aperture 26 onthe lower plate 18 of the shield. The free end of the latch 2-1 engagesa slot 27 formed in the lower plate 18 of the shield. Saidfree end isalso provided with a finger or pin 28 extending transversely of saidlatch 24 to prevent the withdrawal of the free end of the latch throughsaid slot 27 of the shield. The latch 21 is also preferably providedwith a finger piece 29 by means of which the latch 24 may be adjustedand the front plates 17 .of the shield may also be provided with afinger piece:

or knob 30 for moving said plate, if desired. A deflecting plate 31 maybe formed on or attached to the upper portion of the main frame orcasing of the ventilator to break the force of the wind and to preventthe wind from striking directly onto-the aper-i tures 10 of the frontplate or casing of the ventilator. The lower plate 8 of the mainframe ofthe casing of the ventilator is pref erably inclined upward from thewindow sash for the purpose of deflecting the air upward toward theapertures 10 of the easmg.

13 and be operable independently of each the corresponding aperture ofthe adjacent side of the casing may be omitted.

hen the device is in use a current of air entering the interior of thecasing of the ventilator is deflected upward by the inclined plate ofthe ventilator and confined to some extent within the interior by thedefleeting plate 31, and passes through the apertures 10 of the casingto the interior of the building. The quantity of air desired to passthrough the casing may be regulated by the slide 12-13 and the admissionof air through the casing may be entirely shut off by said slide whendesired. In addition to regulating the quantity of air desired to passthrough the casing of the ventilator by means of said slide the shieldl718 may be also used for that purpose. When the shield is in an openposition, as shown in Fig. 4, it has but little effect in controllingthe passage of air through the casing of the ventilator, but when in aclosed position, as shown in Fig. 5, the lower plate 18 of the shieldlimits the quantity of air that can pass through the apertures 10 of thefront plate 7 of the casing, and the upper plate 17 of said shield whenin such position acts as a deflector on the air passing through theaper- Having thus described my invention,

1 plates,

In the construction herein shown the slide is made of two plates 12-13formed integral with and at an acute angle to each otherfi If desiredthe upper plate 12 of the casing may be formed separately .from theplate what I claim as new and desire to secure by Letters Patent is:
